Hey there! As a supplier of Valve Type Lightning Arresters, I often get asked about the best installation positions for these crucial devices in a substation. So, I thought I'd share some insights based on my experience in the industry.
First off, let's understand why valve type lightning arresters are so important. They're designed to protect electrical equipment from the damaging effects of lightning strikes and other transient over - voltages. By diverting the high - energy surges to the ground, they prevent costly damage and ensure the reliable operation of the substation.
Near the Transformer
One of the most common and important installation positions for a valve type lightning arrester is near the transformer. Transformers are the heart of a substation, and they're extremely vulnerable to over - voltages. A lightning strike can cause a huge spike in voltage that can fry the transformer's windings and insulation.
Installing a valve type lightning arrester close to the transformer helps to limit the voltage across the transformer terminals. When a surge hits, the arrester quickly conducts the excess current to the ground, keeping the voltage within a safe range for the transformer. This way, we can avoid expensive repairs and downtime.

At the Entrance of the Substation
Another key location is at the entrance of the substation. This is where the incoming power lines enter the substation. Lightning can strike the overhead lines miles away, and the resulting surge can travel along the lines towards the substation.
Placing a valve type lightning arrester at the entrance acts as the first line of defense. It intercepts the surge before it can penetrate deeper into the substation. This not only protects the internal equipment but also reduces the overall stress on the other arresters installed inside the substation. Our arresters are built to handle high - energy surges at the substation entrance, ensuring maximum protection.
Along the Busbars
Busbars are used to distribute electrical power within the substation. They connect various components such as transformers, circuit breakers, and switchgear. A lightning surge can travel along the busbars and affect multiple pieces of equipment simultaneously.
Installing valve type lightning arresters along the busbars helps to maintain a uniform voltage level. They prevent the surge from propagating and causing damage to different parts of the substation. By strategically placing arresters at regular intervals along the busbars, we can create a comprehensive protection system. If you're looking for arresters for busbar protection, our Composite Insulator Zinc Oxide Arrester is a great option.
Near Sensitive Equipment
In a substation, there are often pieces of sensitive equipment like relays, control panels, and communication devices. These components are particularly susceptible to over - voltages, and even a small surge can cause malfunctions or permanent damage.
Installing valve type lightning arresters near these sensitive devices provides targeted protection. The arresters quickly divert the surge away from the equipment, ensuring its proper operation. For example, if you have a control panel that manages the substation's operations, a nearby arrester can safeguard it from lightning - induced surges. Our Zinc Oxide Arrester On Pole can be easily installed near such equipment for effective protection.
Considerations for Installation
When deciding on the installation positions, there are a few things to keep in mind. First, the distance between the arrester and the equipment it's protecting is crucial. The shorter the distance, the more effective the protection. A long lead length can increase the inductance, which may reduce the arrester's ability to quickly divert the surge.
Second, the grounding of the arrester is of utmost importance. A proper grounding system ensures that the surge current can be safely conducted to the ground. The grounding resistance should be kept as low as possible to maximize the arrester's performance.
Third, the environmental conditions at the installation site need to be considered. Factors like temperature, humidity, and pollution can affect the arrester's performance. Our valve type lightning arresters are designed to withstand a wide range of environmental conditions, but it's still important to choose the right location based on the specific conditions of the substation.
Conclusion
In conclusion, the installation positions of valve type lightning arresters in a substation are carefully chosen to provide comprehensive protection. Whether it's near the transformer, at the entrance, along the busbars, or near sensitive equipment, each location plays a vital role in safeguarding the substation from lightning - induced surges.
